According to Germany's Autobild, Volvo's working up a diesel hybrid version of its new C30 hatch, which the company will show off at Michelin's annual alternative energy fest, Challenge Bibendum in Shanghai later in 2007. It'll be a series hybrid, where the engine turns a generator that can either charge the batteries or power an electric motor that drives the transmission. But the internal combustion engine in this case will be a diesel, and the system may have plug-in capability. No word on whether the car will be a concept, or for series production, but company reps say Volvo is serious about bringing the car to market. But are they serious serious? – Mike Spinelli
